The "Casualties of War" trailer invites you future XCOM commanders to take it to the aliens and it looks pretty intense. On display: several revamped versions of the enemy types from the 90's original and lots of over-the-shoulder gunplay.

So what are your thoughts on the look so far? This trailer is selling up the death and devastation of a full-on alien attack, but I'm really more curious about some of that old-school XCOM experience which was usually tense, waiting for aliens to pop up on some currently unexplored part of the map to take you out. Here's hoping developer Firaxis brings some of that same tension with their new title.

XCOM: Enemy Unknown will be available for the PS3, PC, and Xbox 360 on October 9th.
